Curious what your running for your initial and total timing?
If you have to have that gear reduction sound, another option may be to wrap the headers that are in close proximity to the starter with that heat reflective insulation. I had to wrap one of my torsion bars and my speedometer cable with some because my 2 inch TTI's came close to them. It's pretty amazing stuff.
